Tuning the JVM GC to reduce garbage collection time will speed up application performance. If you agree with that statement then I encourage you to listen to this episode where I have Stefano Doni, CTO at Akamas, walk us through 4 Java Tuning Facts & Myths.

If you want some visuals try to catch his presentation from this years Performance Summit called "How AI optimization will debunk 4 long standing Java tuning myths"
